JOSEPH WARREN WATTLES, OF CANTON, MASSACHUSETTS.

SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 431,731, dated July 8, 1890.

Application filed March 14, 1890. Serial No. 343,932. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH WARREN WAT- TLES, a citizen of the United States, and a resident of Canton, county of Norfolk, and State of Massachusetts, have invented certain new and useful Improvements in Supports for Spinning-Spindles, of which the following is a specification.

My invention relates to that class of spindle-bearings which are made up in whole or in part from a soft yielding material, and has for its object not only the simplification of parts, but also the more secure holding of the step in place than has been possible with the constructions heretofore in use.

To these ends the invention consists in the peculiar combination, with the bolster-holder, of the bolster-tube, step, and locking devices, all as will hereinafter more fully appear.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation of a bolster -holder, bolster-tube, step, spindle, and bobbin, showing an embodiment of my invention; Fig. 2, a vertical longitudinal section of the same with their adjunctive parts, taken axially through the spindle, the upper portion of which is shown in elevation; and'Fig. 3, a detached sectional elevation of a portion of the bolstertube, showing the grooves through which the circulation of the lubricant and the locking of the bolster-tube in place are respectively efiected.

In all the figures like letters are employed to designate corresponding parts.

A indicates the bolster-holder, through or by means of which the bolster-tube, spindle, and other co-operative parts are or may be secured to the spindle-rail or other support. In the construction of this holder any of the well-known forms may be employed. I prefer, however, to make use of that design which is illustrated and described in United States Letters Patent No. 415,336, granted to me November 19, 1889, to which reference may be had, the same being provided with a suitable reservoir a in its upper end for reception and storing of the lubricant, and with a nut a, engaging with the threaded portion a upon its shank, all as shown in the Letters Patent aforesaid.

Located in a cylindrical chamber a extending downward from the bottom of the reservoir a, with which it connects, to near the lower end of the holder is the bolster-tube B, which is preferably fitted thereto sufficiently tight as to prevent all lateral movement therein, and is provided with a cylindrical orifice 1), extending axially of the same throughout its entire length. In addition to the orifice thus described this bolster-tube is also provided with longitudinal grooves 11 in its outer surface extending downward from points some distance above the bottom of the reservoir to its lower end, and is likewise provided with suitable ducts 19 leading through its walls from the bottom of said grooves, whereby the circulation of the lubricant is facilitated. I

Beneath the bolster-tube B in the cylindrical chamber a is arranged the step 0. In the construction of this step any appropriate soft yielding material may be employed. I prefer, however, to make use of felt, which is cut into disks of the proper size and superimposed the one upon the other in the bottom of the chamber a as shown at c c c in Fig. 2; but it is obvious that any other soft yielding filamentous material may be employed, if desired. As thus constructed and arranged, the step is securely held in place by means of the bolster-tube B, which is firmly pressed down upon the same and there confined by the groove b in its periphery, engaging with a pin a, passing through the walls of the chamber a The groove b being arranged'at right angles to the grooves b, and the two grooves connecting, provision is thereby made, as will be seen, not only for holding the bolster-tube pressed down upon the step, but also for removing and replacing the same from and in the chamber a the rotation of the tube in one direction when in such chamberserving to engage the groove 19 with the pin a and thereby locking the bolster-tube in its depressed position, and the rotation in the other to disengage it therefrom, leaving the said tube free for removal from and replacement in the chamber, as desired.

From the chamber a the bolster-tube extends upward some distance above the reservoir a, and is provided near its upper end, in the walls of the orifice b, with a circumferential groove Z), to arrest the upward flow of the lubricant along the spindle, and with ducts b leading therefrom to the outside of the bolster-tube, to conduct the lubricant thus arrested back to the reservoir a, a sleeve or guard D, loosely surrounding the upwardlyprojecting portion of the bolster-tube and resting in said reservoir, serving to protect the lubricant from dust and other foreign substances as it flows down along the outer side of the latter into the former, all as shown in the Letters Patent aforesaid, to which reference has been made.

Mounted in the bolster-tube B is the spindle E, the lower portion or pintle of which is made of the proper size and shape to fit the upper end of the orificeb for an inch or more of its length, and thence tapers to its lower end, where it rests upon the step 0, and thereby supports the spindle against the action of gravity, a collar e being secured near its lower extremity to prevent undue gyration of the spindle when in rotation, as well as the wearing of such spindle down into the soft yielding step beyond a certain distance. The upper portion of the spindle above the top of the bolster-tube which receives the bobbin F may in like manner, taper toward its upper end, and carry fixedly secured to it a collar 6, to the lower end of a sleeve e depending from which, so as to surround the upper end of the bolster-tube, may be supported awhirl a through which and the usual driving-band (not shown) the rotation of the spindle may be effected, or the upper portion of such spindle may be otherwise constructed, the particular form thereof not being essential to my present invention. struction, as will be seen, I not only provide more efficient means for securing the holder and step in place than hitherto employed, but greatly simplify the parts, and effect other advantages not necessary to enumerate herein.

In the foregoing I have described the best means contemplated by me for carrying my invention into practice; but I wish it distinctly understood that I do not limit myself "thereto, as it is obvious that I may modify the same in various ways, or use some of the By this conparts without the others, and still be within the spirit thereof.

Having thus described my invention and ing upon the step, and locking devices for holding it in that position, substantially as described.

2. The combination, with a bolster-holder provided with a cylindrical chamber and a step formed from soft yielding material arranged in such chamber, of a bolster-tube, also arranged in said chamber and pressing downward upon the step, and lockin g devices for holding it in that position, substantially as described.

3. The combination, with a bolster-holder provided with a cylindrical chamber, a step formed from soft yielding material arranged in said chamber, and a spindle, of a bolstertube,also arranged in such chamber-and pressing upon the step, and locking devices for holding it in that position, substantially as described.

4. The combination, with a bolster-holder provided with a cylindrical chamber a and a step 0, composed of a soft yielding filamentous material arranged in such chamber, of a bolster-tube B, also arranged in said chamber and provided with grooves 1) b and a pin a, substantially as described.

5. The combination, with the bolster-tube holder A, provided with a cylindrical chamber a, a step 0, composed of'disks of felt, arranged in such chamber, and a spindle provided with a collar 6 near its lower end, of a bolster-tube B, arranged in said chamber and provided with grooves Z) W, and'a pin a ,substantially as described.

In testimony whereof I have hereunto set my hand this 3d day of March, 1890.
